Thermocouples are among the most commonly used temperature sensors in catalysis. They consist of two different metals joined at one end, generating a voltage proportional to the temperature difference between the joined end and the reference end. Their advantages include:
- Wide Temperature Range: They can measure a broad range of temperatures, making them suitable for various catalytic processes. - Fast Response Time: They quickly respond to temperature changes, providing real-time data essential for dynamic control. - Durability: Thermocouples are robust and can withstand harsh industrial environments.
